[issue47066] Convert a warning about flags not at the start of the regular expression into error
New submission from Serhiy Storchaka : This warning was introduced in 3.6. The reason is that in most other regular expression implementations global inline flags in the middle of the expression have different semantic: they affect only the part of the expression after the flag. But in Python they affect the whole expression. It caused confusion and was a source of bugs. After 5 releases it is a time to convert this warning into error. In future we can allow global inline flags in the middle of the expression with different semantic. It is safer if one or more intermediate versions will raise an error. -- components: Library (Lib), Regular Expressions messages: 415544 nosy: ezio.melotti, mrabarnett, serhiy.storchaka priority: normal severity: normal status: open title: Convert a warning about flags not at the start of the regular expression into error type: behavior versions: Python 3.11 ___ Python tracker <https://bugs.python.org/issue47066> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue44405] add program passed as string to dis module.
Serhiy Storchaka added the comment: Neither of tokenize, ast or symtable modules support passing the source string as argument. If add this feature in the dis module, we will need to add it in all other modules with similar CLI. I do not think it is practical. You always can pass the source string via stdin. And you do not even need to pass /dev/stdin as argument, stdin is the default. I usually use it with rlwrap. It allows to use some editing and history. rlwrap ./python -m dis I propose to close this issue and open a new issue for documenting the CLI of the dis module. -- ___ Python tracker <https://bugs.python.org/issue44405> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue46981] Empty typing.Tuple
New submission from Serhiy Storchaka : There are two empty typing.Tuple. They have the same repr but are not equal. >>> from typing import * >>> t1 = Tuple[()] >>> t2 = t1.copy_with(()) >>> t1 typing.Tuple[()] >>> t2 typing.Tuple[()] >>> t1 == t2 False >>> t1.__args__ ((),) >>> t2.__args__ () The only differences is that one has empty __args__, while other has __args__ containing an empty tuple. There is a code purposed to make __args__ containing an empty tuple in this case. What is the purpose? It is not pure theoretical question. This affects unpacked TypeVarTuple substitution. With natural implementation Tuple[Unpack[Ts]][()] is not equal to Tuple[()] and I still have not figured which and where code should be added to handle this special case. It would be easier if such special case did not exist. Built-in tuple does not have a special case: >>> tuple[()].__args__ () -- components: Library (Lib) messages: 414892 nosy: gvanrossum, kj, serhiy.storchaka priority: normal severity: normal status: open title: Empty typing.Tuple ___ Python tracker <https://bugs.python.org/issue46981> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue45390] asyncio.Task doesn't propagate CancelledError() exception correctly.
Serhiy Storchaka added the comment:
Also Future.result() and Future.exception() can raise a CancelledError. So a
CancelledError raised in a task may not contain a message passed to
Task.cancel().
import asyncio
import random
async def main():
fut = asyncio.Future()
fut.cancel()
async def job():
if random.random() < 0.5:
await asyncio.sleep(2)
fut.result()
await asyncio.sleep(5)
task = asyncio.create_task(job())
await asyncio.sleep(1)
task.cancel("cancel task")
await task
asyncio.run(main())
You need to catch a CancelledError raised in a coroutine and re-raise a new
CancelledError with the specified cancel message if the task was cancelled.

[issue46829] Confusing CancelError message if multiple cancellations are scheduled
Serhiy Storchaka added the comment: For reference, the msg parameter of Task.cancel() was added in issue31033. It seems that the initial use case was for debugging. I do not see how it differs from the following example: r = random.random() if r < 0.5: x = 0 else: x = 0 1/x In the traceback we see the line where an error occurred but we do not see a line which lead to this error. -- ___ Python tracker <https://bugs.python.org/issue46829> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue46622] Add an async variant of lru_cache for coroutines.
Serhiy Storchaka added the comment: async_lru_cache() and async_cached_property() can be written using that decorator. The implementation of async_lru_cache() is complicated because the interface of lru_cache() is complicated. But it is simpler than using _lru_cache_wrapper(). def async_lru_cache(maxsize=128, typed=False): if callable(maxsize) and isinstance(typed, bool): user_function, maxsize = maxsize, 128 return lru_cache(maxsize, typed)(reawaitable(user_function)) def decorating_function(user_function): return lru_cache(maxsize, typed)(reawaitable(user_function)) return decorating_function def async_cached_property(user_function): return cached_property(reawaitable(user_function)) -- ___ Python tracker <https://bugs.python.org/issue46622> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue46622] Add an async variant of lru_cache for coroutines.
Serhiy Storchaka added the comment: I think that it would be simpler to add a decorator which wraps the result of an asynchronous function into an object which can be awaited more than once: def reawaitable(func): @wraps(func) def wrapper(*args, **kwargs): return CachedAwaitable(func(*args, **kwargs)) return wrapper It can be combined with lru_cache and cached_property any third-party caching decorator. No access to internals of the cache is needed. @lru_cache() @reawaitable async def coro(...): ... @cached_property @reawaitable async def prop(self): ... -- ___ Python tracker <https://bugs.python.org/issue46622> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
